A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Overview

This OEM hot surface igniter (part number 1171306) lights the burners on your ICP / Tempstar / Heil RGS121HRBA0AAAA gas furnace. On a call for heat the control board powers the igniter, which glows red-hot to ignite the gas as it flows across the burners. The matching wiring kit (1188370) is included to ensure a clean, factory-spec electrical connection. Hot surface igniters are brittle and wear out over time — they crack, develop hairline fractures, or fail to reach ignition temperature, leaving you with no heat, a furnace that clicks but never lights, or a unit that locks out after several failed ignition attempts.

Document — Photograph the igniter mounting position and wiring routing before removal.
Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter. Never touch the new element with bare fingers — skin oils cause early failure.

Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light promptly.
